Cell phone having wireless charging function
A coil module is disposed inside an electronic apparatus and receives prescribed power. The coil module includes a loop coil, a plate-like magnetic body that is disposed on the loop coil, and a conductive member that has prescribed conductivity and is disposed parallel with the plate-like magnetic body and on a surface, opposite to a surface on which the loop coil is disposed, of the magnetic body. The conductive member projects outward relative to at least a portion of a circumferential surface of the magnetic body.
1. A cell phone having a wireless charging function, comprising:
a coil module configured to receive power, the coil module including:
a planar magnetic body having a first surface and a second surface opposite from each other, and a cut-out portion therein, and
a loop coil laid over the first surface of the planar magnetic body, two ends of the loop coil extending from the loop coil through the cut-out portion of the planar magnetic body and being coupled to two terminals, respectively; and
a battery disposed over the second surface of the planar magnetic body, the battery overlapping at least the cut-out portion of the planar magnetic body.
2. The cell phone of claim 1 , wherein the battery has a generally rectangular shape.
3. The cell phone of claim 1 , wherein the planar magnetic body does not overlap with the two terminals of the loop coil.
4. The cell phone of claim 1 , wherein the loop coil has a generally circular shape.
5. The cell phone of claim 1 , wherein the loop coil is formed of a conductive wire wound into a loop form.
6. The cell phone of claim 5 , wherein the loop coil is wound a plurality of times in a concentric manner.
7. The cell phone of claim 1 , wherein the two ends of the loop coil extend generally in parallel with each other and are coupled to the two terminals.
8. The cell phone of claim 1 , wherein the battery is larger in size than the planar magnetic body.
9. The cell phone of claim 1 , wherein the battery overlaps the two terminals of the loop coil.
